Description

Technical Field

[0001] This utility model relates to the technical field of packaging material processing equipment, specifically a drying device for processing waterproof and oil-proof packaging paper. Background Technology

[0002] In the production of waterproof and oil-proof packaging paper, the drying process is the core step to ensure the curing effect of the coating and that the moisture content of the packaging paper meets the standards. It is necessary to achieve uniform drying of the packaging paper through a stable supply of hot air, while avoiding potential quality-affecting factors during the processing.

[0003] In the production of waterproof and oil-proof packaging paper, traditional equipment relies on the main hot air system to dry the packaging paper. However, due to the boundary effect, the hot air coverage at the edge of the packaging paper is significantly weaker than that at the center, resulting in a much higher moisture content at the edge and making it prone to mold and coating adhesion. At the same time, during the drying process, the packaging paper generates static electricity due to moisture loss and friction with the conveyor belt. This static electricity attracts dust in the workshop, which then blocks the mesh of the main hot air outlet, further exacerbating the uneven airflow. This reduces drying efficiency and causes unstable product quality. Therefore, we need to propose a drying device for processing waterproof and oil-proof packaging paper. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for processing waterproof and oil-proof packaging paper, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drying device for processing waterproof and oil-proof packaging paper, comprising an upper shell and a conveyor, wherein the upper shell is installed on the top of the conveyor, and the inner wall of the inlet and the inner wall of the outlet of the upper shell are both connected with detachable high-temperature resistant heat-insulating soft curtains in the vertical direction, and the heat-insulating soft curtains are arranged to fully cover the width direction of the inlet and the outlet. An antistatic component for preventing static electricity in the packaging paper is installed on the top of the upper housing. One end of the antistatic component penetrates the upper housing and extends into the interior of the upper housing.

[0006] Preferably, the electrostatic component includes a high-voltage generator, an ion bar, a first fan, and a first outlet pipe. The high-voltage generator is installed on the top of the upper housing. The high-voltage generator and the ion bar are electrically connected. The outlet end of the first fan is connected to one end of the first outlet pipe. A first valve is installed on the surface of the first outlet pipe.

[0007] Preferably, the ion air bars are symmetrically installed inside the upper housing, and each ion air bar has a mounting block symmetrically installed on its top. The end of each mounting block away from the ion air bar is connected to the inner wall of the upper housing, and the end of the first air outlet pipe away from the first fan is connected to one end of the ion air bar.

[0008] Preferably, an air outlet plate is installed on the inner wall of the upper housing, the interior of the air outlet plate is hollow, and strip-shaped air outlet holes are evenly opened at the bottom of the air outlet plate. An industrial hot air blower is installed on the top of the upper housing, and the air outlet end of the industrial hot air blower is connected to a second air outlet pipe. A second valve is installed on the surface of the second air outlet pipe.

[0009] Preferably, the other end of the second air outlet pipe is connected to a third air outlet pipe and a fourth air outlet pipe. The end of the third air outlet pipe away from the second air outlet pipe extends into the interior of the upper housing and is connected to the top of the air outlet plate. The end of the fourth air outlet pipe away from the second air outlet pipe extends into the interior of the upper housing and is connected to one end of the ion air bar. A third valve is installed on the surface of the fourth air outlet pipe.

[0010] Preferably, a controller is installed on the top of the upper housing, and a temperature sensor and a vision sensor are installed on the inner wall of the upper housing.

[0011] Preferably, the controller is electrically connected to the temperature sensor and the vision sensor respectively, and the controller is also electrically connected to the first fan, the industrial hot air blower and the high-pressure generator respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes electrostatic components and controllers to neutralize the static electricity in packaging paper through the combination of ion air bars and a high-voltage generator. This prevents dust from being attracted by static electricity and clogging the main hot air outlet, significantly enhancing the airflow stability of the main hot air system. It also reduces the decrease in drying efficiency caused by mesh blockage. Simultaneously, it supplements hot air to the edges to improve uneven drying while greatly reducing the risk of mold growth and coating adhesion on the packaging paper edges. This reduces the product scrap rate and ultimately achieves the dual functions of uniform drying and dust prevention, ensuring stable product quality. Attached Figure Description

[0019] An air outlet plate 9 is installed on the inner wall of the upper housing 1. The interior of the air outlet plate 9 is hollow. The air outlet plate 9 is used to deliver hot air to the packaging paper. The bottom of the air outlet plate 9 is evenly provided with strip-shaped air outlet holes 10. The strip-shaped air outlet holes 10 are used to blow the hot air in the air outlet plate 9 evenly onto the packaging paper. An industrial hot air blower 11 is installed on the top of the upper housing 1. The industrial hot air blower 11 is used to generate hot air. The air outlet end of the industrial hot air blower 11 is connected to a second air outlet pipe 12.
